摘　　要：针对传统海图生产中资料处理工序多、集成困难的特点,提出面向海图生产的多源数据集成方案,对该方案中的空间基准统一、数据模型统一和要素编码的统一等问题给出了相应的集成方法,并采用数据格式转换的方式进行了集成实验,为数字海图生产和数据的进一步融合奠定了基础。In view of the discrepancies of tedious multiple work steps and poor multi-source data integration in traditional chart design processing,multi-source data integration scheme for the purpose of chart production is presented. The specific integration method is proposed according to the scheme on following integration issues,as unification of spatial datum,data model and feature coding unification. Also,the integration experiment is carried out by means of data format transfer,which lays the foundation for digital chart production and further chart data fusion.
